1. Introduction to Engineering Thermodynamics
Engineering thermodynamics is the branch of physics that deals with the energy transfer and conversion processes in engineering systems. It provides a framework for analyzing and designing systems that involve the transfer of heat, work, and mass.
Thermodynamics has a long history, dating back to the early days of the Industrial Revolution. The first steam engine was invented in 1712 by Thomas Savery, and the first practical steam turbine was developed in 1884 by Sir Charles Parsons.
These early inventions were based on the principles of thermodynamics, which were first developed by Sadi Carnot in 1824.
Today, thermodynamics is used in a wide variety of engineering applications, including the design of power plants, refrigeration systems, air conditioning systems, and combustion engines.
1.1. Fundamental Concepts and Principles of Engineering Thermodynamics
- Energy: Energy is the ability to do work. It can exist in many different forms, such as heat, work, and mass.
- The first law of thermodynamics: The first law of thermodynamics states that energy cannot be created or destroyed, but it can be transferred from one form to another.
- The second law of thermodynamics: The second law of thermodynamics states that the entropy of an isolated system can never decrease.
1.2. Historical Development and Applications of Thermodynamics in Engineering
Thermodynamics has a long and rich history, dating back to the early days of the Industrial Revolution. The first steam engine was invented in 1712 by Thomas Savery, and the first practical steam turbine was developed in 1884 by Sir Charles Parsons.
These early inventions were based on the principles of thermodynamics, which were first developed by Sadi Carnot in 1824. Carnot’s work laid the foundation for the modern science of thermodynamics.
Today, thermodynamics is used in a wide variety of engineering applications, including the design of power plants, refrigeration systems, air conditioning systems, and combustion engines.
2. Energy and the First Law of Thermodynamics
Energy is the ability to do work. It can exist in many different forms, such as heat, work, and mass.
2.1. Definition of Energy and Its Different Forms
- Heat: Heat is the transfer of thermal energy from one object to another due to a difference in temperature.
- Work: Work is the transfer of energy from one object to another due to a force acting through a distance.
- Mass: Mass is a measure of the amount of matter in an object.
2.2. Explanation of the First Law of Thermodynamics and Its Implications
The first law of thermodynamics states that energy cannot be created or destroyed, but it can be transferred from one form to another.
This law has a number of important implications, including the following:
- The total amount of energy in the universe is constant.
- Energy can be transferred from one object to another, but it cannot be created or destroyed.
- The efficiency of a machine is always less than 100%.
2.3. Application of the First Law to Solve Problems Involving Energy Transfer and Conversion
The first law of thermodynamics can be used to solve a variety of problems involving energy transfer and conversion.
For example, the first law can be used to calculate the amount of heat that is transferred from a hot object to a cold object, or the amount of work that is done by a machine.
3. Properties of Pure Substances
A pure substance is a substance that has a uniform chemical composition throughout.
3.1. Explanation of the Concept of a Pure Substance and Its Properties
- Intensive properties: Intensive properties are properties that do not depend on the amount of substance present. Examples of intensive properties include temperature, pressure, and density.
- Extensive properties: Extensive properties are properties that depend on the amount of substance present. Examples of extensive properties include mass, volume, and energy.
3.2. Discussion of the Use of Property Tables and Charts to Determine the Properties of Pure Substances, Fundamentals of engineering thermodynamics eighth edition
Property tables and charts are graphical representations of the properties of pure substances.
These tables and charts can be used to determine the properties of a pure substance at a given state.
3.3. Application of the Ideal Gas Law and Other Equations of State to Predict the Behavior of Pure Substances
The ideal gas law is a mathematical equation that describes the behavior of gases at low pressures and high temperatures.
Other equations of state, such as the van der Waals equation, can be used to predict the behavior of gases at higher pressures and lower temperatures.
